Megosztás a facebookonThese screw holes are usually covered with blind plugs and separable bearings such as tapered roller bearings. When unloading a small-diameter bush, it is best to use a stepped punch. The oil is pumped through the oil hole on the tapered shaft to expand the inner ring to disassemble the bearing.
The small diameter of the punch matches the inner hole of the bushing. Several cutouts are provided on the housing shoulders.The punch is made of steel, the top of the hammer is processed into a spherical shape, so that the end contacting the workpiece is usually inlaid with soft metal, such as copper, aluminum, etc. Remove the outer ring of the interference fit.
Tighten the screws evenly while removing them. Use spacers to remove them with a press or gently tap them. Bearings with a large width can only be disassembled by using oil pressure and drawing fixtures together. A method of heating a part in a short time to expand the inner ring before drawing. It is better to use the nut as a stopper China INA Bearings .
The oil pressure method is adopted for the inner ring disassembly of large bearings. The large diameter of the punch is about 0. For the disassembly of large-diameter bushes and rolling bearings, casings are often used.5mm smaller than the outer diameter of the bushing. Disassemble the relatively small bearing with adapter sleeve, support the inner ring with the stopper fastened to the shaft, turn the nut back several times, and use the spacer to knock it off with a hammer.
To remove them from the holes, the method of unloading is also commonly used. When unloading, the hammered end face of the bushing should be cushioned. Sliding bearing bushings and rolling bearing jackets are interference fits in the holes
Megosztás a facebookonPerform rough scraping according to the distribution of colored points on the bearing.Introduction, what is a jaw crush bearing? Jaw crusher is the abbreviation of the so-called jaw crusher. When surfacing welding, the surfacing welding process should be selected correctly to prevent the bending deformation of the distracting shaft.Measure the level of the spindle.
Then, the main bearing and connecting rod bearing are assembled. To reduce the damage of the broken jaw bearing, the accuracy of the bearing can be changed from ordinary level to C3 level, which has higher accuracy.
Coarse and fine scraping of upper and lower tiles First install the two lower bushes in the bearing seat, then apply a layer of display agent (such as red lead powder) on the spindle, install the spindle in the bearing, and rotate it two or three times in the forward and reverse directions, and then take the spindle out. Solution: When the equipment is in operation, read the instructions carefully, and select appropriate lubricants according to the instructions, and add oil regularly. Large rocks that exceed the size of the feed inlet must be blasted twice before entering the inlet to extend the service life of the crusher .
If this kind of phenomenon occurs, only scrap it or change the shaft material for other purposes. Measure the top clearance, side clearance and axial clearance of the old bearing bush. Important factors that cause the high temperature of the jaw crush bearing: A positive rake angle can be used for the rough scraping stage.
Solution: At this time, replace the end cover and sealing sleeve of the jaw crusher, or loosen the upper bearing cover on the heating end of the frameClutch Release Bearings manufacturers bearing seat, press it into the frame bearing seat groove with the fuse and the embedded cover, and then set the bearing Cover to eliminate the rotation of the embedded cover. When the eccentric shaft enters the movable jaw, an iron hammer is used to move the jaw, and the eccentric shaft is loaded into the movable jaw by the interaction, without damaging the bearing on the eccentric shaft.
